It’s rare that Hefty meets a derg that can match his own appetite, but Wolf certainly gives him a run for his money

Commission for LoneWolf on Discord

#furry #furryart #fat #fatfurry #fatfur #blob #blobface #fatfetish
Wolf the dragon floating in space having fattened up to an enormous size. The greedy dragon drinks deeply from two tubes each linked to spaceships in orbit around him, both carrying four spherical tanks of some kind of food or gainer supplement. The image shows both his huge body in full and a zoom in of his face in the upper left-hand corner. Wolf revels in their sheer size and calls for even more as he greedily sucks down yet more food. The yellow-orange text around the image describes actions or sounds produced by Wolf as he eats and grows. The main text reads: “Yes!, Give me more!” “More ships, more food, more fat, more me!” “More!” “More!!” “MORE!!!”
